A) 14
B) 12
C) 16
D) 18
Correct Answer: B
Solution :
Sol. Using prime factorsation: |
\[60=2\times 2\times 3\times 5={{2}^{2}}\times 3\times 5\] |
\[84=2\times 2\times 3\times 7={{2}^{2}}\times 3\times 7\] |
and \[108=2\times 2\times 3\times 3\times 3={{2}^{2}}\times {{3}^{3}}\] |
\[\therefore \] Maximum number of participants that can be accommodated in each room \[=HCF(60,84,108)\] |
= Product of the smallest power of each common prime factor in the numbers. |
\[={{2}^{2}}\times 3=4\times 3=12\] |
So, option [b] is correct. |
